CFPUA temporarily stops adding fluoride to water at treatment plant
“We have disabled some equipment,” said Styers.
When asked about how long the investigation will take, Styers was not able to provide an estimate.
“After we got our system back up and running yesterday, we did start to investigate at the plant the mechanical equipment,” said Styers.
How long were fluoride levels too high in drinking water?
Fluoride levels returned to below 2 mg/L at 9 a.m., according to CFPUA’s Director of Engineering Carel Vandermeyden.
“We take samples every four hours when the plant is in operation,” said Vandermeyden in an interview yesterday.
What do scientific experts say about fluoride in tap water?
“But for a few hours over the course of one day, I’m not worried for anybody.” Fluoride added to tap water has been proven to protect teeth from decay, according to David Howard, assistant health director with New Hanover County.
“The ranges of intakes producing these opposing effects are not far apart.” The Centers for Disease Control and Prevention (CDC) fully supports regulated fluoride in tap water to prevent tooth decay, writing that the safety and effectiveness have been shown by several scientific and public health organizations using study reviews and panels.
“Experts have weighed the findings and quality of available evidence and concluded that there is no association between water fluoridation and any unwanted health effects other than dental fluorosis,” according to the CDC.
Four Myths About Water Fluoridation That People Shouldn’t Swallow
Four Myths About Water Fluoridation That People Shouldn’t Swallow.
Fluoride isn’t natural Fluoride is a naturally occurring substance found in rocks that leaches into groundwater; it’s also found in surface water.
The type of fluoride commonly found in many rocks and the source of the naturally occurring fluoride ion in water supplies is calcium fluoride.
So regardless of the original compound source, the end result is the same — fluoride ions in the water.
Fluoridated water doesn’t work Evidence for water fluoridation dates back to US studies in the 1940s, where dental researchers noticed lower levels of tooth decay in areas with naturally occurring fluoride in the water supply.
The NHMRC review found children and teenagers who had lived in areas with water fluoridation had 26-44 percent fewer teeth or surfaces affected by decay, and adults had 27 percent less tooth decay.
Most studies that claim to show adverse health effects report on areas where there are high levels of fluoride occurring naturally in the water supply.
There is, however, evidence that fluoridated water is linked to both the amount and severity of dental fluorosis.
Therefore, making up infant formula with fluoridated tap water at levels found in Australian (0.6-1.1 parts per million) is safe, and does not pose a risk for dental fluorosis.
Indeed, Australian research shows there is no association between infant formula use and dental fluorosis.
Bottled water versus tap water
Bottled water versus tap water.
Australians who only drink bottled water are turning their backs on the benefits of water fluoridation, according to the Australian Dental Association (ADA) NSW.
Speaking on the topic recently, ADA (NSW) president Dr Sabrina Manickam said, “Drinking tap water with fluoride has added benefits for your oral health.” ADA NSW recommends tap water as the primary choice of drink for everyone.
It is the most hydrating drink.
Dr Manickam added: “Water fluoridation prevents dental decay in all ages.
It is a safe, effective and ethical way of providing benefit to everyone in the community, especially those who are disadvantaged.” Water fluoridation remains the cornerstone population health measure in preventing dental caries, having been endorsed and recommended by more than 150 scientific, health and political organisations throughout the world, including the World Health Organization.
